My first motherboard, back when a 386 MB cost nearly a grand, was destroyed by ESD due to the jackass sales buffoon doing me a huge favor walking it out of it ESD-Safe bag, on the flat of his palm like a pizza tray, from one side of the shop plainly visible behind their front counter about 15 feet to the bench. With rubber soled shoes on a Nylon carpet. I knew I should've said something when I 'heard' the "bzzzzzt" in my head, but no. I just HSD to get it home straight-away, to torture myself, thinking I must've done some hook-up error, but no. "It's Dead, Jim." What is a dcent dual power supply these days? For +15 to 18V & -15 to 18V? Funny how Aliexpress has so many ads for the same models, ranging 3 to 1 in price for the same dang model. So, I think for a PS I will buy local.

It's fairly common for these simple diy circuits to interact when fed from the same power supply. Try using large bypass capacitors (100uf to 1000 uf electrolytics, + to positive power and - to negative) . where power is input to each circuit. That should stabilize things. Also a AC coupling cap at the oscillator output may help. Try a 10uf bipolar electrolytic cap in series with the output, before going into the volume pot.

What is a maximum frequency i can generate with this, and also if i want to generate frequency of 300mhz what should I use?
@Golkun13 жыл бұрын
for 300MHz use a quartz oscillator

Its bad practice to conect the potenciometer like that, the correct way to conect it like a reohstat (like u doing) its to conect the center tap to the "unused" pin.
@Golkun13 жыл бұрын
yes, this would be good practice, because the resistance of the potentiometer wont get indefinite when the center tap looses contact.

I short both legs of the pot together, so it's the same

hi , do you know how to make a cv input control for the 40106, ive built a baby 8 seq , but have not finde the way to control the oscilator properly , thank!

It sounds like the synth solo in “Lucky Man” by Emerson Lake, and Palmer

You should become a teacher! You are very good at explaining and showing exactly what you are doing. Thanks for taking the time to share your knowledge!

I've never built a module but I 'd like to start , which basic one do you recommend?

In my quests for electronics knowledge and know how on the web, I’m often exposed to a few famous chips and circuits, especially in synth circuits: the Phase Detector and VCO of a 4046 and the elusive Wien Bridge Oscillator which uses a regular old light bulb for temperature compensation, as a thermistor?! That sentence just aroused a curiosity in me just now: what’s the difference / relationship between temperature compensation - and - phase detection?! I mean, they are both detecting something basically: the PLL is always looking out for that clock’s leading edge, while the light bulb thermistor is trying to normalize the temperature, it lights up when it gets too hot(?!). BTW that’s a beautiful old personal computer lab - synth station combo you’ve got there in the Heath kit! It reminds me that I have bitten off WAY MORE than I could chew regarding kits and electronics projects ever since I read about YOU in Ray Wilson’s book! I thought, ‘oh! That’s a really beautiful panel! What?! It’s a DIY effort?! Oh geez! I could really claim my music for my own and get my hands even closer still to this creative process if I could actually MAKE my synths!...’. It’s been almost six years now, and I’ve just had my first component actually explode right off of its PCB! Thank you for doing this stuff! It’s great!

right on, what a testimonial :) Thanks a lot! (I don't know how to answer your question about thermistors :( )

The resistance of a light bulb filament increases as it gets hotter. (Light bulbs self-regulate the current that flows through them. It starts high at switch-on, and drops as the filament heats up and its resistance increases, reaching a stable level of current, temperature, and resistance.)

Very cool. Looking into building a DIY modular for my Beringer Crave.

Great video, it helped me to add an lfo to a resonant filter i've built. Thank you so much.
